Warm oil in a small skillet over medium heat. Saut? onion until it has softened. Combine onion with remaining ingredients except apple cider, dark brown sugar and the 2 teaspoons of prepared yellow mustard. Mix well. Place the meat in a loaf pan, and smooth its surface. Bake the ham loaf about 1 hour.

While the loaf bakes, combine the apple cider, brown sugar and 2 teaspoons prepared yellow mustard.

Remove the pan from the oven, and let it sit for at least 10 minutes before cutting the loaf.
